ACIS System

ProboStat™ ACIS is a sample holder dedicated for AC conductivity measurements and 2-electrode impedance spectroscopy on small disk samples at high temperatures and under controlled atmospheres.

Special design of the hot-zone parts facilitates mounting and replacement of test samples compared with the standard ProboStat™ furnishment.

The test sample rests in a support tube, is contacted by electrode connects, and held stably in place with a spring load assembly. The setup is assembled in a single chamber mode and can be fed with virtually any gas. The sample holder is designed to operate at near-atmospheric pressure, but can be pumped to low vacuum, or hold up to 15 bar. Electrical connections are made via standard coax cables.

ProboStat™ ACIS Compatibility

The system is supplied with a standard ProboStat™ base unit and can be expanded for any sample geometries and measurements that ProboStat™ can support.

The ProboStat™ ACIS works well with all instrumentation such as impedance spectrometers, LCR meters and potentiostats from Solartron, PAR, Novocontrol, Autolab, Gamry, HP/Agilent, etc.
